The characteristics of the official kiln in the Southern Song Dynasty are not mainly manifested in its decoration, but in its natural beauty like Yuquan, solemn, elegant and mysterious. In artistic style, they win by glaze color, are good at modeling and are famous for their patterns. These products embody the unique artistic style of oriental people, which is simple, lofty and simple. Imperial kilns burn palace porcelain, so it is required to be as perfect as possible. In the early works, in order to glaze all the utensils, dishes and other utensils were generally fired in Zhi Ding, but Zhi Ding was bigger and thicker than Ruzhou official kiln, with as many as 20 pieces. Later, I often use mats to burn. Although there are dull marks on the bottom, it is coated with a layer of iron tire protection slurry, which makes the product more distinctive.
The Southern Song Dynasty official kiln porcelain is characterized by inheriting the dignified and simple modeling and rich enamel of the northern famous kilns such as Bianjing official kiln porcelain in the Northern Song Dynasty and Ruguan kiln porcelain in Henan Province, and absorbing the thin-walled thick glaze of the southern famous kilns such as Yueyao and Longquan kiln, with bright glaze color and exquisite modeling. The combination of northern art and southern craft created a peak in the history of China celadon. It is also a great and outstanding contribution to world culture and art. After the demise of the Southern Song Dynasty, official kilns were destroyed, craftsmen were separated, skills were lost, and rare treasures were handed down. 1989, a piece of celadon from the Southern Song Dynasty official kiln was sold in Hongkong for HK$ 25 million, setting a record in the auction history of ancient pottery in China.
The blue glazed porcelain of the Southern Song Dynasty official kiln is famous for its black glaze. Indeed, as the ancient book says, it has three characteristics, namely, purple mouth and iron feet, black and gray tires; Stripes, gold wire; Thick glaze is thin, the glaze color is opaque and sapphire. The reasons are as follows;
Purple iron feet, black gray tires: this is because its tires are made of tire mud mixed with purple mud, so the tire mud contains high iron oxide and burns in a reducing atmosphere, so the tires are black; The exposed part of the foot and the thin glaze along the mouth show the black color of the tire, which is called "purple iron foot"

Thick glaze is thin and opaque, showing a sapphire color: the glaze is opaque, with a certain amount of crystals and more iron oxide coloring, which has a strong jade texture. According to the refining atmosphere, the firing color can change from pink to fried rice yellow. In addition, due to the high potassium content in the glaze and high viscosity at high temperature, the glaze layer can be kept thick without flowing, thus forming the characteristics of thin tire and thick glaze, and even products with thicker glaze than tire appear.
